If you haven't already, make sure the SD card you wish to use with Windows Phone is installed in your phone. In order to use it, the SD card must be present during initial installation of the operating system as it will be formatted and become part of Windows Phone's 'Unified storage system'.

Connect your phone to your PC using a USB cable.

Power up the device in Bootloader mode. Do this by pressing and holding down the power button and the volume down button simultaneously.

Run this program as an administrator: Right-click, Run as administrator.

You have succesfully installed Windows Phone.

After you've completed the initial configuration wizard, go to "Settings", "About" to check the version number and available storage.

In order to use Windows Live Services, required by features such as Facebook integration and the Windows Phone Store, you need to obtain an activation code through Microsoft. You can contact Microsoft by phone or chat. I will not cover this procedure here, but you can find information and tips about it elsewhere online.

After HSPL installation I have installed the MAGLDR but after rebooting it became HTC white screen with not showing any red letters or ROM version. Several times I have followed the recovery instructions but there are no any changes.Please can you help me.Now only you for me.Expecting your help, let me to wish you a bright future you for such issue.Thank you. vimukthiwansa@gmail.com

@Vimukthiwansa Dhammapriya while htc logo appears keep on pressing call drop button till few seconds recovery will be open otherwise change the file your file might be crypt or try other usb cable and usb port this ill fix i hope so best of luck

I'm having a major issue. Every worked smoothly until I finished the MAGLDR installing (a screen prompt said the MAGLDR installation will take more than 10 mins but mine was done under 30 seconds!). But in reboot it didn't load MAGLDR bootloader instead its show a purple circular arrow and nothing else. When I tried to rerun the MAGLDR program, I noticed that on the 3rd screen with "Current information about your PDA" heading the image version space is now blank. When I continue the process is still successful but the situation is not changed. I've tried it multiply times with the same results. Can anyone help me?

I feel bad for anyone having problems. Me and others have used the instructions above successfully many times.

Here are some suggestions:- Use a direct connection to a USB port on your computer (no hubs).- Many problems can be traced back to a faulty or unsupported SD card. If you have one, try another one. In the context of troubleshooting you could try without one.- Run flash tools executables (e.g. HSPL4.exe and ROMUpdateUtility.exe) from a local hard drive.

If you need further help, the XDA Developers Forums are a rich source of information: http://forum.xda-developers.com/.

Excellent Posting and Step by Step guide!!! Want to ADD here one thing,if you are installing under a Windows 8 environment or Windows 7 or Vista then please use Administrative Privileges (Right Click and RUN AS ADMINISTRATOR option) to DWI.EXE file to avoid Installation Failure of the ROM Update.Thumbs Up and keep up the good work.

Hello DaveI tried the instructions like running HSPL and MAGLDR when the MAGLDR was finished installing my phone didn't reboot to MAGLDR to continue the process. it just stopped on white screen (htc) and I'm not able to have access to my previous windows as well.Before installation I didn't copy anything/ troubleshoot/ format my SD card, can you please tell me what is the problem and what I can do to fix this.Thanks & Regards,

thanks alot! great work Dave!everything is working almost perfect, only too low volum when making a call (max 10/10) and speaker function does not work :(i am also missing scheduled sms sendings.do you work with updates? let us know plz.thanks again.

Sorry to bother you...but can you help me? I pressed the MAGLDR link in the instructions. But when when I selected "ROMUpdateUtility.exe" and downloaded it, nothing happened. I'm an administrator, but still nothing happens. :( Help please?

I installed this everything you said, even i activate Windows LIVE ID, it works great, but I have one problem... When battery is charging, it stops around 91%, then I unplug and plug charger again, and it shows 100%... Sometimes I have to reset the phone, to get battery full... Can someone tells me what is the problem, and can it be fixed? Thanks

good work mate , don't know why all these other people are having sooo much problems instructions is precise and easy to follow ,make sure you rip to your desk top.my hic up is that I live in Australia rang help desk for activation code for hd7 .operater said that the phone is locked and I need to speak to htc rep in orange in the uk?

Thanks for posting this post which seems working like a charm.I have htc hd 2 with win 6.5. Before i proceed need to know how i can back up contacts and msgs. HTC syc manager is not supporting htc hd2. secondly.If i stuck somewhere how i will restore or reintall 6.5

Hi i'm really stuck, do you think you could do a video? i'm at the USB Flasher Mode Part (USB Flasher mode: "Wait USB...USB".) and i just cant seem to do anything after like open certain files or folders... NEED HELP URGENTLY :(

All, please note there is also plenty of info over at XDA-Developers about activation, there's even a little app to generate the correct type of puk code or whatever it is that they ask for. Of course, you can't tell them you have a HD2 ;) its a "HD7". The phone up method worked fine for me, I have been using pdaimate jam rom for ages, no problems

Everyting works fine, only the battery drains to fast...max 19 hoursbut is it possible to switch back tomagldr? i tried everything but its still boots to wp7.. even without the SD card it starts wp7 :( how to boot back to winmo6.5?

Hello I just got up to the last part where you install the ROM, but when i click on DWI.exe it says no data found. I have tried downloading the file again but same problem. I have used my htc hub and also regular usb's but still same problem...

Hi Dave, First of all my thanks and compliments for the great step-by-step guide. Even I managed to update my HD2. But now I am having some strange and apparently unrelated issues with the phone and I was wondering/hoping if you by looking at the issues, you could see what went wrong:1) My Wifi connection is shaky. Without SD card, I can find the available networks, but when entering the Password, it keeps returning as an incorrect password (which it isn't)2) I keep returning to the set-up page as if each time i start-up the HD2, it is the first start-up. Time settings, date, language preferences etc. are all gone3) Changing the language - in my case to the Indonesian Language - has no impact whatsoever

Perhaps I need to re-do the install, but is that at all possible? Ok, again my thanks for an exellent instruction guide and I hope you (or anyone else ftm) can help me with the final tweeking of my phone.4) The SD card - formatted to NTFS - is not recognized

Hi Dave, just an update. Managed to reinstall the ROM and guess what ... all seems to be working just fine, with here and there a couple of glitches (such as powering on and off for no obvious reason).

Hello Dave, I have installed with a 4GB SD card and remaining space is 199KB. How can I tranfer the files in the sd card to another one so I can have more free space to others applications ?? I use Windows 8.1 in a notebook and using a USB cable notebook does nor recognize my HD2.

Hi there, I stock into a position that it seems I need help , I did this thing and every thing was all right , after installation of MAGLDR the device hanged on boot screen and nothing is happening until now , I tried to reinstall the program but the result is the same , I cant even turn it back to the previous version , would you please help me on this thing ?

This worked a treat, but I would like to upgrade my installed micro card with a larger one. I know that it is not a strait swap. I have looked into cloning but there does not seem to be anything on the card to clone i.e. hidden files etc. Anyone got an idea how to do this?

Hi Dave, 1000 thanks for your help.It did really worked, 6 months ago, I have tried to install System Android, I have buzzed completely my HTC HD2, was simply dead, I've even took to the repair, and Guy couldn't repair it, then he said; you should send it to HTC, but it may cost a lot. So I tried last night, before putting my HTC in the trash. Voila all's working, and I have new version of Win Mobile 7 on my HTC now. Great page, thanks again for helping us. take care..

Thanks, for posting this tutorial, appears easy to follow, so I'll try it. I just had an ..."accident" with my Nokia Lumia 820 WPh8 so until I decide if it's worth fixing it or getting something newer/better I have to resort/rely on my older but trustworthy HTC HD2. I did n't want to go as far back as Windows Mobile 6.5 so I'll have to try this WPh7.8.

One quick question: You wrote "Download and run MAGLDR (ROMUpdateUtility.exe)". But, when I click the MAGLDR link, I arrive at a page with a bunch of files including ROMUpdateUtility.exe. What am I supposed to do: Download ONLY ROMUpdateUtility.exe and run it as admin, or download ALL these files "under" the MAGLRD" link? And if your intention was to do the second, why the link takes us inside the MAGLDR "folder" and not a "level" above that so it's easier to download the entire MAGLRD directory with one click.

Am I missing something or it's just a small glitch in the instructions?

Finally, what is all this fuss about calling/chat Microsoft to activate Live Services, etc. I mean if this is not working how is this a functional ROM. Without Live.com support who can I be able to sync our phone and download our contacts, etc. At least can you explain a bit more or provide a link, or at a minimum what are we googling/yahooing/binging for here!?!

ΟΚ, Ι did it everything is very well documented, it works, windows phone 7.8 on the HD2 runs fine, very smooth, very responsive, very slick looking. I love it but unless I can activate it with MS all this will be an exercise on futility. If anyone knows a sure-fire way to get an activation code please post it of contact me at xwpisonoma at gmail.

Unfortunately I bricked my HTC HD2 with the above instruction. Don't know what I did wrong.Step ROMUpdateUtility.exe was finished very quickly, phone rebootet, but it got stuck on the screen with the pink turning donut. Waited for very long, finally removed the battery. Now no button shows any reaction any more :-(
